you wake up at 6am because this is what the liberal market has wired your nerves to do for optimal returns of the exploitation of your person.
6 is the most reasonable acceptable limit for consented alienation.
Before that, the time starts with a 5am and it's an other realm of productivity that is associated with either discipline when done by financially independant free humans or with misfortunate slavery for the working class who has to wake up this early for various reasons ranging from commute distance or the specific needs of the industry that employs their bodies.
6 is the last psychological and symbolic limit that people feel comfortable with when confronted to their enslavement.
And in most of the cases a culture of morning routine has emerged to cope with such a condition to associate optimal preparation of the body for a day of productivity for the sake of the market and at the same time to imbue this time with a simulacrum of meaning, of stability, an identity also, humans feel comfort in viewing the ceremonies they do over and over again as part of their intimate identity. stretching, cooking sunny side eggs exactly the same way every time, doing coffee a certain way, swallowing vitamins, even going for a jog...
anyway this culture of trying to make this time that was robbed from your sleep a moment you have some control over through your own landmarks even though it is not your time anymore.
the day was taken from you and the next ones for decades to come.
But when you wake up at 6am and crack open a bottle of high proof lager first thing in the morning. You regain your freedom, you get to be in charge again. By simply impairing yourself you bring your productivity down for the day and revolt against the requirements forced onto you.
it's the first act of the day and it is revolt
And with the buzz you become impervious to any shaming tactic, any punishment system the market has for the disobedient.
You become invincible
